MILES C. HUYETT, OF DETROIT, MICHIGAN, ASSIGNOR, BY MESNE ASSIGN- MENTS, TO CECELIA E. HUYETT AND ADIE O. ROLLER, OF SAME PLACE.

CAR-WINDOW VENTILATOR.

SPECIFICATION forming part of Letters Patent N 0. 405,312, dated June 18, 1889. I

Application filed August 2'7, 1888. Serial No. 283,869. (No model.) i

To all whom it may concern.-

Be it known that I, MILES O. HUYETT, a citizen of the United States, residing at Detroit, county of IVayne, State of Michigan, have invented a certain new and useful Improvement in Car-l/Vindow Ventilators; and I declare the following to bea full, clear, and exact descriptionpf the invention, such as will enable others skilled in the art to which it apper- 1O tains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure 1 represents a perspective view of [5 my improved car-ventilator. Fig. 2 is a horizontal section of the same.

Itis the object of my invention to provide for railway-cars, and more especially sleepingcars, a removable ventilator for the windows,

2c and for use more particularly in warm weather. It is also my object to prevent as far as possible the dust and cinders from covering the passengers. This latter I accomplish with the aid of my improved ventilator, by which an air-current is drawn in through the ventilators at the top of the car and discharged through the window-ventilators.

In the drawings, A is the main frame of the ventilator, and is made such a length that it will fit in the window-sash underneath the window when the latter is raised. This main frame may be divided in the middle and provided with hinges a, so that when not in use it may be compactly folded. One-half of the frame A is filled with an imperforate panel B, while the balance is either left open or is provided with a screen-netting B. At the forward end of the frame is a guard 0, made either of wood or metal and standing at right angles to the frame. This guard may be pro vided with hinges c, to admit of its being folded in against the frame, and with a brace c, for holding it at right angles to the frame when in use. Near the opposite end of the frame from the guard is a curved piece of metal or wood D, having one edge (1 fastened to the frame and the other edge standing some little distance out from the frame. If desired, an additional guard, as shown by the dotted lines in Fig. 1, may be hinged to the top of the frame A and extend out in a horizontal direction as far as the guard 0, being supported at the end by said guard. The edges of the frame may be provided with strips of rubber or other material for the purpose of making tight joints between the ventilator and the adjoining faces.

The operation of the ventilator will now be understood. \Vhen the train is moving, the air, together with any dust or cinders, will strike the guard O and will either pass downward or in a horizontal direction around the edge of the guard, as shown by the' arrows in Fig. 2. This guard is made wide enough, so that the current of air after passing around the edge of the guard C will not again strike the frame A until it reaches the panel B. It then passes .along until the deflector D is reached, when it is deflected outward.

It will be readily seen that the air-current passing rapidly past the opening B and no air entering therein will tend to suck the air out of the car, and thus ventilate it without any dust or cinders being thrown on the passengers.

The deflector D prevents the air from banking either in the window-casing corner or in front of the guard in the next rear window and eddying back into the opening B. The guard E prevents any air-current that may come over the top of the guard C from entering the opening B.

What I claim is 1. A car-ventilator consisting of a frame substantially coextensive in length with a Window of the car and provided at one end with a guard arranged at a right angle with the frame and at the other end with a deflector forming a more or less acute angle with the frame, substantially as described.

2. A car-ventilator adapted to be fitted in the window-casing of a car underneath the window, consisting of a frame provided at one end with a guard standing at right angles to the frame, an opening or screen in the frame for the exit of air from the car, and a deflector adapted to throw the air from the side of the car, substantially as and for the purposes described.

3. A portable car-ventilator adapted to be placed underneath a car-window when the latter is raised, consisting of a frame provided with an. opening or screen and a guard attached thereto just for\\"ard of said opening or screen, substantially as and for the purposes described.

4c. A car-Ventilator consisting of a frame provided with a hinged guard at its forward end, adapted to prevent air from entering an opening or screen in said frame, and a dc- Ilector adapted to throw the air-current from, the de of the car, substantially as described.

5. In a ear-ventilator, the combination, with frame provided with an opening or screen in the forward half, a deflector at the rear end, and an outstanding guard at the forward end, of a guard adapted to prevent air from passing overthe top of the outstanding guard and into the opening or screen, substantially as described.

(.3. A car-window ventilator consisting of a frame adapted for insertion beneath the sash provided with an exterior outstanding guard at its forward end, said frame imperl'orate along its rear half and provided with a screen or opening at its forward half, substantially as described.

7. A ear-window ventilator consisting of a frame adapted for insertion beneath the sash provided with an exterior outstanding guard at its forward end, said frame imperforate along its rear half and provided with a screen or opening in the forward half, and a deflector on the exterior at the rear end, substantially as described.

In testimony whereof I sign this speeifieatien in the presence of two witnesses.
